Investigators on Monday released an updated photo of Ruben Cepeda, who is considered to be armed and dangerous. A warrant with $1 million in bail was issued for his arrest.

He is suspected of shooting Viridiana Rodriguez Nunez, 18, at their apartment on Fig Street near Mission Avenue Saturday night.

The Medical Examiner’s Office said Monday that Rodriguez died from a gunshot wound to the abdomen. The teen’s unborn child did not survive.

The victim’s sister told 10News, U-T San Diego’s media partner, that she was sleeping in another room when she heard the gunshot. The victim was four months pregnant and looking forward to being a mom, the sister said.
